Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a welding jig for a heavy truck chassis connecting beam. Background Technology

[0002] Heavy truck chassis connecting beams are generally welded together, relying on operators to mark lines on a platform and then weld them together. This not only results in low work efficiency but also easily leads to poor product consistency and difficulty in controlling dimensions within tolerance range, affecting the overall production progress and product quality.

[0003] Currently, there are some welding fixtures for connecting beams in existing technologies, but due to the significant structural differences between connecting beams from different manufacturers, they are not interchangeable. For example, CN215469100U, a welding fixture for connecting tubular crossbeams and tubular crossbeam flanges of heavy trucks, is not applicable to the welding of individual connecting beams of heavy truck chassis. Utility Model Content

[0004] This utility model provides a welding jig for the connecting beam of a heavy truck chassis, which can solve the problems pointed out in the background art.

[0005] A welding jig for a heavy-duty truck chassis connecting beam includes a workbench. Connecting plate positioning seats are provided on both sides of the workbench along its length. A beam positioning plate is provided between the two connecting plate positioning seats. Connecting plate positioning plates are slidably mounted on the inner sides of the connecting plate positioning seats on both sides, and are driven to slide by a positioning plate driving component to adjust the distance between the two connecting plate positioning plates. The connecting plate positioning plate is provided with several connecting plate positioning components, and the connecting plate positioning seats are provided with several connecting plate fixing components. The beam positioning plate is provided with several beam positioning limiting components and beam fixing components.

[0006] Preferably, the connecting plate positioning seat is provided with a plurality of guide bushings, and the connecting plate positioning plate is provided with guide shafts that cooperate with the guide bushings to achieve sliding fit.

[0007] Preferably, the positioning plate driving component is a driving cylinder disposed on the positioning seat of the connecting plate.

[0008] Preferably, the connecting plate positioning component is a positioning pin, and the connecting plate fixing component and the beam fixing component are both corner cylinders.

[0009] Preferably, the beam positioning and limiting component is a limiting plate, and the limiting plate has a limiting groove.

[0010] Beneficial effects: This utility model provides a welding jig for heavy truck chassis connecting beams, which is applicable to the welding operation of individual heavy truck chassis connecting beams. It is easy to operate, improves production efficiency and welding accuracy, thereby reducing production costs and improving product quality. Attached Figure Description
